Bitwarden CLI npm Package Compromised in Supply Chain Attack
In April 2026, attackers compromised Bitwarden's CLI by uploading a malicious version (2026.4.0) to npm, available between 5:57 PM and 7:30 PM ET on April 22. The malicious package contained credential-stealing malware that harvested developer secrets, including npm tokens, GitHub authentication tokens, SSH keys, and cloud credentials. The malware exfiltrated this data by creating public GitHub repositories under the victim's account. Bitwarden confirmed the incident, stating that the breach was limited to the npm distribution channel for the CLI and did not affect end-user vault data or production systems. The company revoked compromised access, deprecated the malicious release, and initiated remediation steps immediately.

Organizations must enhance their security measures to protect against such vulnerabilities, as similar attacks have been linked to the threat actor known as TeamPCP, who previously targeted developer packages in other supply chain attacks.
